Things I liked:It looks and feels great. It shoots accurately within its range. Things I would have changed:It was fun while it lasted, but it is rather expensive for how poorly it was made and quick that it broke. The Co2 cartridge integrated with the clip. Why? You are just asking for problems.What others should know:I have had this gun for under two months and I have had 3 clips break on me. The problem is they have the Co2 cartridge in the clip, the connection to the pistol doesn't seem to work well. When I first got the gun, I shot for a few weeks and then the clip started to leak, I thought oh well, I'll just use another clip. A few days later the second clip started to leak also. On to the third clip, that one lasted a few weeks before it started to leak as well. I have read reviews about over tightening causing leaks, I have been very careful with this gun. I have never had this problem with another air gun. Clips are about $25 ea. At this point, I'm just going to throw the gun out. When I say they leak I mean they make a roaring hissing noise, when they are supposed to be sealed. You can only manage to get of about 6 shots before the whole co2 cartridge leaks out. This is a clear design flaw with this pistol. Don't bother buying it.

Things I liked:Accurate from 30 feet. Will hit a 10 meter NRA Air Pistol target paper center ring. All metal, has a nice weight to it. Slider, safety, all functioning. Well constructed. Recoil is realistic. Buy it from Pyramyd Air and purchase their 10 for $10.00 test to ensure you get a well-tested, certified functioning product.Things I would have changed:The CO2 loading procedure in the magazine. It is a bit of a pain when screwing the cap and tightening it. Sometimes the cap is off and the CO2 doesn't get punctured. Trial and error. Need to always find the sweet spot to properly seat the CO2 cap.
Makes a loud noise. I mean really makes a loud bang.What others should know:Use Pellgunoil everytime you load a CO2 in the magazine. It'll make the O rings last. Get it here at Pyramyd Air.

Things I liked:This is a real good replica of a full-size Sig handgun. It has a very realistic weight and heft. It is the most accurate airsoft handgun that has passed through my hands. I am using 0.20 BB's and Crosman CO2's. This is very impressive.Things I would have changed:The takedown lever seemed a little fragile. I like to oil the slide rails and exterior of the barrel with Rem Oil using a Q-Tip.What others should know:I only load 15 at a time, and shoot 5-shot strings to let the CO2 warm up a bit between shots. It lets me get the most out of a CO2 cartridge. This gun uses a fair amout of CO2 to blow back the slide, but I get a decent amount of shots.

I ordered a couple of these pistols form the past and most recently. Some came with "Sig Sauer" trademark on the grips, and some didn't! Any reason for this? I contacted a couple of sites asking about this and if replacement grips were purchasable; It just feels like I received a couple of unfinished products. =/

Jerry from USA:

That question would need to be answered by the manufacturer

Peter from USA asked:

Does this gun have a single and double action trigger?

Dan the Man from USA:

Yes
